Is this the way to associate an empty replacement value for "\cr". When I do not place a space after
? I get an error.
(defvar texsym-cluster
("\\alpha" . ?α) ("\\cr" . ? ))

How is that var used?
?c is the read syntax for a character. There is no "empty" character of
course. Can you use strings instead as replacements?

I have a keybinding sequence "H-s" that would remove "\cr" text from view
I am using texsym-cluster in this way
(defun texsym-predicate (start end _match)
"Prettify mathematical expressions defined by tex syntax.
Matches START with a backslash and END with a word constituent
[a-zA-Z0-9]. Uses the prettify functionality of `prog-mode'."
(not (or (memq (char-before start) '(?\\))
(memq (char-syntax (or (char-after end) ?\s)) '(?w))
(nth 8 (syntax-ppss)))) )
(defun prettify-symbols-cluster ()
"Set keywords and corresponding glyph."
(setq-local prettify-symbols-alist texsym-cluster)
(setq prettify-symbols-compose-predicate 'texsym-predicate))

Ah, so for usage in `prettify-symbols-alist'. I guess you could use a
zero-width space as replacement, i.e., ?\N{ZERO WIDTH SPACE}.
Bye,

Would this be the exact code?
("\\cr" . ?\N{ZERO WIDTH SPACE})

Ok, I found it in the Elisp Manual {2.4.3.2 General Escape Syntax}.
